so i dyed my carpets black. used RIT dye from walis-mart under 3 bucks!
got a chemical spray bottle think it held 1 liter.
used 1/4 dye and 3/4 water.
set nozzle to heavy mist and got-r-done.
instructions on the dye says it will stain plastic.
so u used a rag wet with windex to wipe off all the plastic parts right after.
it looks sweet, kinda like when u get new wheels or tiers makes it look like a hole new vehicle.

You did a great job; if you had not indicated you dyed it I never would have know. Looks like you're ready to start your own business.

Any downfalls to doing this? This is something I would love to do to mine!

Over time this can sometimes make the carpet look even worse. Just depends on upkeep and if you did a good job. It will need to be reapplied every couple years if it wears off. I have seen the end result after years of not taking care of it from a car we wholesaled, not very nice.
